Similar to two materials in the coating part melting together, and coating thickness can reach 100 microns, so high corrosion resistance, salt spray test 96h no problem, equivalent to 10 years under the usual environment; Cold galvanizing is electroplating at room temperature. Although the thickness of the coating can also be controlled, the binding strength and thickness of the coating are relatively low, so the corrosion resistance is poor.
Blade rope in the world has been widely used in the military, prison, government agencies, banks; Living community wall, private residence, villa wall, doors and Windows, highway, railway guardrail and border line and other protection security.
As for the protection operation of galvanized barbed rope column, replace the column which is corroded or misinterpreted and so on, and place the replacement area from the beginning, and reinforce the column with unstable pile foundation in time. There is also about the protection of galvanized barbed rope itself, to repair the damaged local, will be severely replaced by rust.
Now hexagonal mesh is used in a large number of Bridges, piers and bridge buttress inclined plane protection, bridge buttress inclined plane there are many kinds, people according to the inclination of the inclined plane to choose the right hexagonal mesh, and in the case of steep slope, people will use gabion mesh gravity protection wall. As we all know, the use of hexagonal net for protection can protect the natural environment while protecting the bridge, which can not only green the ecological environment, but also prevent soil erosion.
5, according to the wire diameter thickness to adjust zinc dipping time
Galvanized iron wire is very common in practical application, some people think that galvanized iron wire will not rust, in fact, it is not. Metal corrosion is caused by the chemical or electrochemical action of the surrounding medium. According to different media, it is divided into atmospheric corrosion, soil corrosion, seawater corrosion, bacterial corrosion and so on. Atmospheric corrosion is more common, because metal products in the process of processing, transportation and storage, when in contact with the atmosphere, there are always atmospheric corrosion conditions.
Hot dip galvanizing is a kind of external treatment technology in the production of fasteners. The common varieties of hot dip galvanizing fasteners are electric galvanizing, powder galvanizing, mechanical galvanizing and hot dip galvanizing. Wire factory according to different requirements of customers for fasteners, different hot-dip galvanized surface treatment. Galvanized layer and steel is a metallurgical connection, become a part of the steel surface, so the durability of the coating is more reliable.

Ordinary installation of blade thorn rope on the wall and the height of the wall in two meters up and down the general construction costs in a dozen yuan a meter, but if it is said that the height of the prison construction ordinary wall has reached four or five meters so that the construction cost of each meter is about 30 or 40 yuan, mainly because of high altitude operation risk degree is relatively large reason. The construction cost is different, but the price of blade thorn rope is the same, often the construction cost is higher than the product, which is the thorn rope factory recommends customers to use better quality blade thorn rope, which eliminates the cumbersome time and cost of subsequent demolition and installation.
But there are some necessary precautions in the production of galvanized wire. Remove all tools and piles on the work site and equipment that hinder activities, and slowly put the wire into the cylinder during pickling to prevent acid splashing on the body. When adding acid, the acid must be slowly poured into the water. Do not pour water into the acid to prevent acid spillage and injury. Workers should wear protective glasses when working. Then in the handling of wire and other items, it is strictly prohibited to push hard.
The galvanized requirements of the parts to be plated: the surface of the parts to be plated should be smooth, and there is no dirt that cannot be removed by pickling method. Such as paint, grease, cement, asphalt and excessive rotten harmful substances; All welds of welded components shall be sealed without air; Pipe fittings and containers must have exhaust and zinc inlet holes; The workpiece should be finished welded steel pipe without thread, if any thread should be protected.
In order to remove defects such as surface film layer and surface inclusion of large roll galvanized wire, it can be treated by conventional technology. The presence of small homogeneous particles of large denier in the tank can stabilize the foam layer, but the accumulation of too many solid particles can cause explosion. Activated carbon mat to remove surface active substances, or through filtration to make the foam less stable, these are effective measures; Other measures should also be taken to minimize the intake of surface active substances. The electroplating speed can be significantly reduced by the introduction of organic matter.

When this ore is specially refined into metallic iron, carbon, silicon, manganese, and other elements are added to it, so that the refined material is called general pig iron, which is also the material for the initial grade. According to the different requirements of the industry, different weights of alloy ingots are prepared in the smelting furnace according to the standard, such as weaving, Ming, paper, Lang, silicon, etc., and this smelting material is called combined gold ore.
Heavy hexagonal mesh is made of low carbon steel wire galvanized large wire braided, the tensile strength of steel wire is not less than 38kg/m2, the diameter of steel wire can reach 2.0mm-3.2mm, the surface of steel wire is usually hot galvanized protection, galvanized amount can reach 500g/m2.
That layman how to identify the amount of galvanized, can use the following three methods. Professionals told us that the surface layer of the high-zinc barbed rope would not be particularly smooth due to the zinc behind it, which could be found when comparing the two products. Although the zinc barbed wire zinc layer is thin but relatively smooth.
According to the galvanized iron wire manufacturer, galvanized iron wire is the selection of excellent low carbon steel, through drawing molding, pickling rust removal, high temperature annealing, hot galvanized, cooling and other processes. The following points should be paid attention to in the use of galvanized iron wire:
The wire after the first plating, its strength limit is also higher than the first plating, plated zinc and then made of wire not only toughness and high strength. There is a lower figure in the strength limit of galvanized iron wire because of the quality of zinc, because the strength of zinc technology is several times smaller than the wire itself. It is difficult to hot-dip galvanize drawn wires, and it is impossible for finer and very fine wires to be coated with the desired thickness of smooth zinc.
Electric welding net is also known as external wall insulation wire mesh, galvanized wire, galvanized electric welding net, wire mesh, row welding net, touch welding net, construction net, external wall insulation net, decorative net, wire mesh, square eye mesh, screen mesh, anti-crack mesh. Stainless steel electric welding mesh, is made of high quality stainless steel wire row welding, more acid resistance, alkali resistance, welding firm, beautiful, widely used and so on.
Second: positive and negative twisting rope cost-effective
In general, there are not many forms of dog cages, and most of them are reasonable, with trays underneath for cleaning up after your dog. I would like to remind you to make sure that the bottom plate of the dog cage with the square iron bar (that is, the bottom of the cage on the plastic tray) is not movable and can be removed and cleaned because the dog’s feces will stick to it and it will be too troublesome to remove it. There is the size of the larger wire dog cage, usually below is no wheels, this is very inconvenient, to move up will be very heavy, small size wire dog cage is not too hard to move.
The hot plating wire uses zinc-free slag to add hot melt zinc and galvanize, which avoids the traditional heating process and radiates the surface 1653 of zinc liquid surface 4102 to the hot melt zinc, reducing the high temperature oxidation on the surface of zinc liquid. At the same time, the heating body is in contact with the zinc liquid, and the heat is directly transferred to the zinc liquid. The utilization rate of heat energy can reach more than 90%, which reduces the heat radiation of the zinc liquid surface.
